Changes in the peripheral blood flow in legs in response to the cold: own studies using plethysmography

Łastowiecka-Moras E., Bugajska J., Jurczak I.

International Journal of Occupational Safety and Ergonomics

2016

Vol. 22, No. 4

501--507

The thermal environment in the workplace is an important factor which affects workers’ health. During 2011 in Poland, 14,781 workers were exposed to a cold working environment, i.e., 3.8% of persons employed in hazardous work conditions. The aim of this study was to determine the cardiovascular response to continuous (4 °C for 60 min) and intermittent (10 min at 4 °C and 10 min at room temperature alternately) exposure to the cold in 30 healthy men aged 20–27 years. Peripheral blood flow was assessed with impedance plethysmography. Heart rate and arterial blood pressure were monitored with the Holter system. Having assessed the results, it is difficult to say which kind of exposure has a more severe impact on the cardiovascular system. Longer observation and a more detailed analysis would be necessary (e.g., Doppler echocardiography).

Response of olfactory receptors and blood cells of Lake Baikal fish to phenol exposure

Yakhnenko V., Klimenkov I., Pastukhova N.

Environmental Biotechnology

2010

Vol. 6, No. 2

66-73

Exposure to phenol causes ultrastructural disorders in supporting and receptor cells in the peripheral segment of the olfactory organ of yellowfin (Cottocomephorus grewingkii) and in cells in peripheral blood of stone sculpins (Paracottus knerii), yellowfin and perch (Perca fluviatilis). Identical responses to phenol exposure in the blood cells were observed in endemic Lake Baikal fish and in nonendemic fish. Differences were found only in the rate and intensity of the recovery response. Fast activation of immune processes were found in the coastal nonendemic perch, but they were slow in the stone sculpin, a coastal endemic species.
